:dragana, since you are the author of the regressor, bug 1755660, could you take a look?

For more information, please visit auto_nag documentation.

Looks like there has been no test failure recently.

FWIW, it's test-verify, so we'd only see these failures in CI whenever a push happens to touch that specific test file, so I'm not sure how much I'd read into the lack of failures.

It seems this is still happening.
